6.4.3 Selecting a Wireless Channel
You may need to change the wireless channel on which the wireless cable modem
operates when you are in computing, test, and other environments where several wireless
access points may be operating in the 2.4Ghz range.
In some cases, you may want to segment your wireless traffic where a group of devices
operates on one channel and another group operates on another channel, and so on. This
is done by configuring the channel on each wireless access point individually (if you have
multiples). If you have control over only one wireless device in an environment where
there may be several, you can change the wireless channel on your device to one that is
not heavily used.
To change the wireless broadcast channel, refer to Using the Wireless Radio Option on
page 57.
The following diagram displays the channels available in the Americas. Each available
channel is 22Mhz wide. Since channels overlap, it is best to choose channels that have
the least overlap (typically 1, 6, and 11 in the Americas, and 1, 5, 9, and 13 in Europe).
Overlapping channels can cause wireless network performance issues.
